potential energy
an object that is not moving can be in equilibrum. an object moving at a steady speed in a straight line can also be equilibrum.
Gravity
If the speed of a moving object is doubled, the object's kinetic energy must also double, as kinetic energy is directly proportional to the square of the object's speed.
You can tell if another object is moving while you are also moving by observing changes in the position of the object relative to you over time. If the object's position changes relative to your position, it is likely moving, even if you are also in motion. Additionally, you can use external reference points or landmarks to determine if both you and the object are in motion.
The transitive property of motion states that if object A is moving with respect to object B, and object B is moving with respect to object C, then object A is also moving with respect to object C. This property can be used to describe the motion of objects in a reference frame.
Velocity is the speed of an object in a specific direction. It includes not just how fast an object is moving, but also the direction in which it is moving.
This was the essential question on a homework assignment. Speed tells how fast an object is moving but it does not tell the direction. Velocity tells how fast an object is moving and it also tells the direction. When velocity is positive, the object is moving up. When velocity is negative, the object is moving down.
A force will cause a moving object to continue moving. It will also cause the object to move farther and faster until friction slows it down.
A negative velocity in a moving object indicates that the object is moving in the opposite direction of its positive velocity. The consequences of a negative velocity can include a change in position, direction, and speed of the object. It can also affect the object's acceleration and overall motion.
an object moving through a vaccuum
It's not necessary to specify that the object is moving at a constant speed. Any object with no outside forces acting on it does that. It also continues moving in a straight line.
It can be said that the net force applied on the object is zero or that the object is in translational equilibrium. Keep in mind that these terms can also be applied if the object is moving at a constant velocity.
